According to the BBC, Nicholas Newlife placed a bet at 66/1 odds in 2003 that Federer would win seven Wimbledon titles by 2019. For context, Federer finished 2003 with just one grand slam title on his resume. It was his first career Wimbledon title. In the years since, Federer has won six more times at the All England Club, tying him for the most all-time wins. Needless to say, Oxfam made no secret that it was rooting for Federer as he went for his record-tying seventh win, which came over Andy Murray.

Newlife contacted William Hill and requested the Federer bet, according to the BBC. A representative for the bookmaker has since described the request as "unique." According to the Daily Mail, Newlife was a "recluse and asked neighbours to place bets for him."

In both cases, Newlife more or less bet that Federer was about to become one of the most dominant players in the history of tennis. The graceful Swiss star obliged. Newlife passed away in 2009, leaving the bets to Oxfam.

These outstanding sports bets are not the only unusual items bequeathed to the aid organizations over the years. According to Oxfam's website, committed individuals have left items ranging from a dentist's chair to a letter written by Florence Nightingale.
